Romania hydraulic cylinder for vehicles

(Romania hydraulic cylinder for vehicles,produced by Hengyu Hydraulic Cylinder Factory)

hydraulic cylinder for vehicles are widely used in Romania,because of excellent fatigue and impact resistance,high work efficiency,simple structure and reliable operation.So our company has designed hydraulic cylinder for vehicles for customers from Romania.

Introduction to hydraulic cylinder for vehicles:

If the hydraulic cylinder for vehicles is sliding or crawling (stop and go), check whether there is any astringency inside the hydraulic cylinder for vehicles. The internal parts of the hydraulic cylinder for vehicles are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the hydraulic cylinder for vehicles changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the hydraulic cylinder for vehicles or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the hydraulic cylinder for vehicles bore processing is out of whack. Because the piston and hydraulic cylinder for vehicles, guide rail and piston rod are relative If the hydraulic cylinder for vehicles is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling hydraulic cylinder for vehicles weight composition and calculation. The weight of the hydraulic cylinder for vehicles is composed of the hydraulic cylinder for vehicles diameter, the outer diameter and weight of the hydraulic cylinder for vehicles, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

When the oil pressure of the hydraulic cylinder for vehicles inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

In order to ensure the service life of the hydraulic cylinder for vehicles, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the hydraulic cylinder for vehicles, causing damage to the seal and causing leakage in the hydraulic cylinder for vehicles. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

When the hydraulic cylinder for vehicles thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the hydraulic cylinder for vehicles. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the hydraulic cylinder for vehicles still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about hydraulic cylinder for vehicles:

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.

What does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.
